The crack of bad property.External wall elastic coating can effectively solve the problem that building substrate surface due to having the good performance expanded with heat and contract with cold
The destructive crack problem of generation and be received by the market.The main composition of external wall elastic coating is elastic emulsion, vitrifying
Temperature is less than environment temperature, is elastomer under the environment temperature used.External wall elastic coating is because having good elasticity, film
Softness, so having preferable tensile property.However external wall elastic coating causes destruction in effective protection wall from crack
The problem of stain resistance difference is concurrently there are, i.e., elastic soft film coating (especially in the summer of high temperature) surface is easy to after-tack, easily
Dust is adsorbed, the stain resistance and dicoration of external wall elastic film are greatly reduced.
In the prior art in order to improve external wall elastic coating contaminated resistance, mainly reached by following two modes：
One, the amount of filler in external wall elastic formulation for coating material is improved, the less elastic emulsion of external wall elastic coating drying and forming-film rear surface is made
Ash not easy to stick, or smaller filler is used, make the finer and close ash not easy to stick of external wall elastic coating film forming.And the method is apparent
Defect is external wall elastic coating causes its flexibility decrease, especially low temperature elasticity to decline obviously because of the raising of PVC；Two, exterior wall
The lotion of blending high rigidity in elastic coating keeps hardness higher after external wall elastic coating drying and forming-film, stain resistance more preferable.And this
The obvious shortcoming of method is external wall elastic coating causes flexibility decrease especially low temperature elasticity to decline obviously because hardness improves.Institute
To say, the contradiction between external wall elastic coating elasticity and stain resistance now cannot be all solved there are two types of widely applied technology.
Therefore, a elastic emulsion for having good stain resistance again simultaneously with excellent resilience how is developed, is current
The problem of acrylic acid ester emulsion industry.
